OUTLET-BOX.

SPECIFICATION forming part of Letters Patent N0. 714,600, dated November 25, 1902.

Application filed March 12, 1902. Serial No. 97,952. (No model.)

To all whom it may concern:

Be it known that I, ERNEST W. MiiLLnR, a citizen of the United States of America, residing in the borough of Brooklyn, in the county of Kings, State of New York, have invented an Improved Outlet-Box, of which the following is a specification.

The object of myinvention is to construct an outlet-box which shall be specially adapted for use in connection with electric-arc lamps or the larger types of Nernst lamps or other electrical devices which have to be suspended from above, more especially from the ceilings of buildings.

In the accompanying drawings, Figure 1 is a vertical section of my improved outlet-box, and Fig. 2 is an inverted plan View of the same.

In the common practice electric-arc lamps when used in buildings are suspended from hooks fastened in the ceiling, and the conductor-wires are led from adjacent outlets if interior Wiring has been used. I so construct my outlet-box that thelamp can be suspended directly from the box itself, thus providing a self-contained structure complete in itself and dispensing with the separate fitting of the outlet-box and supporting-hook heretofore required.

The outlet-box A, which is to be fitted in place in the ceiling O in any suitable way, is shown in the present instance as cylindrical. It may be. suspended from the floor above by a pipe B, coupled up to the bottom or back of the box, into which is also fitted a pipe 13' for leading in the wires E E for connection with the lamp.

The face-plate of the outlet-box I prefer to make in the form of an open-Work spider D for convenience in connecting up the Wires.

This spider is secured to the face of the box by means of screws 01, fitting holes tapped in the ribs a, formed in the walls of the box.

To the center of this spider is fitted a suspensionhook F with intermediate insulating washers ff. The eye 7c at the upper end of the lamp to be suspended fits over this hook, and a sheetmetal cover or canopy K, adj ustable on the upperpart of the frame of the lamp or the like, may be used to cover up the support and outlet-box, the larger upper end of this canopy or cover fitting against the ceiling O.

I claim as my invention- 1. An electrical outlet-box adapted to be fitted into a ceiling and carrying on its lower face an insulated suspension-hook for an arclamp or the like.

2. An electrical outlet-box adapted to be fitted into a ceiling and having a face-plate carrying a suspension-hook with insulation between the hook and the face-plate.

3. An electrical outlet-box having an openwork face-plate, a suspension-hook carried by the face-plate with insulation between the suspension-hook and the plate.

4. The combination of an outlet-box adapted to be fitted to a ceiling and having an insulated suspension hook with a canopy adapted to be carried by the frame of an arclamp or the like to cover up the suspensionhook and the outlet-box, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ERNEST W. MULLER.
